Specifications

Product Overview

The Series 850 represents premium French door engineering for Upper Keys homes requiring exceptional height capability and enhanced performance. When Pino Windows of the Keys installs these doors, clients gain access to 10-foot door possibilities with optional transoms extending to 132″ total height. This capability opens design options that standard doors can’t accommodate, allowing dramatic entries and connections with expansive ceiling heights.

The 9/16″ heat-strengthened laminated glass provides superior impact resistance compared to thinner configurations. This substantial glass makeup delivers both hurricane protection and security against forced entry. The 5″ maximum frame depth accommodates this thicker glass while providing the structural strength required for larger door sizes. Heavy-gauge aluminum T6 alloy construction maintains frame integrity across these extended dimensions.

Performance & Engineering

Maximum door height reaches 120″ without transom and 132″ with integral transom included. Width configurations handle single door up to 45 9/16″ or double doors reaching 87 1/2″ combined. Design pressure of +80/-80 psf shows enhanced wind resistance compared to entry-level models. Florida Product Approval for Large Missile impact brings these premium doors up to full code compliance for coastal locations.

The 3-point lock on active door leaf and 2-point lock on inactive leaf provide secure closure with distributed engagement around door perimeters. The locking points pull doors tight against weather-stripping while preventing bowing under wind pressure. The 1 5/8″ residential bumper threshold creates proper transition between interior and exterior while maintaining weather seals.

Extruded snap-on glazing beads allow glass service without disturbing door frame construction. Colonial muntins available in 2 1/2″ and 4 1/4″ profiles create traditional French door character. Optional 10″ bottom rail provides substantial elevation when applications require it, though this also increases the step-over height users must navigate.

Energy-efficient Low-E coatings become essential with the larger glass areas these tall doors provide. Solar heat gain through 10-foot door glazing without proper coatings would create enormous cooling loads. Low-E reflects infrared radiation while transmitting visible light, managing heat without sacrificing the brightness and views that make French doors desirable. Glass with argon fill enhances thermal performance.

Integral transom capability distinguishes this door system from simpler configurations. The transom extends total height while maintaining consistent frame appearance and weather protection. This allows full-height glazing in spaces with generous ceiling elevations, creating dramatic connections between indoor and outdoor environments that define high-end Keys architecture.

Keys-Specific Benefits

The outswing configuration remains appropriate for Upper Keys exposure where storms approach from varying directions. Outswing doors naturally resist wind trying to force them inward. The design pressure rating and impact approval ensure these doors maintain their position during extreme weather rather than becoming weak points in building envelopes.

Installation of tall French door systems requires specialized equipment and experienced crews. Getting 10-foot pre-hung assemblies positioned, leveled, and secured demands proper lifting capabilities and multiple installers. The opening preparation must be precisely dimensioned because doors this tall don’t accommodate significant adjustment during installation. Flashing systems need thorough planning to protect expensive installations from water intrusion.

Available muntin patterns include flat-flat and plain ogee-flat profiles in colonial configurations. The larger muntin dimensions provide appropriate visual weight for the substantial door sizes. Matching these muntin styles with existing windows or other French doors on the same property maintains architectural consistency despite different product series.

The Series 850’s capabilities suit Upper Keys properties where ceiling heights or design ambitions exceed what standard doors accommodate. Waterfront homes with dramatic interior volumes benefit from doors that match the scale of their spaces. Contemporary designs featuring generous glazing and indoor-outdoor connectivity rely on products like the Series 850 to execute architectural intent while maintaining code compliance.

Regular maintenance keeps French door hardware operating smoothly. Multipoint locks need periodic lubrication and adjustment to maintain proper engagement. Threshold weather-stripping experiences traffic wear and eventually requires replacement. Hinge tightness should be verified annually to prevent sagging that affects door operation. At Pino Windows of the Keys, we provide comprehensive service for these premium door systems.
